Partial dentures are devices that replace one or more missing teeth on upper maxillary and lower maxillary in order to improve phonetics, aesthetic, chewing, occlusion and to prevent the slipping of natural teeth.
Partial dentures are supported on healthy gums and are held by hooks to the adjacent natural and healthy teeth. They can be more stable than full dentures thanks to their different supports.
There are two types of partial dentures: the partial metal prosthesis made of a chromium and cobalt alloy and the partial acrylic prosthesis.
The partial metal prosthesis is made of an alloy of chromium and cobalt. It contains an acrylic part the same color as the gum to simulation. The metal part is three times thinner than acrylic part so that it makes it lighter and it drives the heat which improves taste sensation. The metallic partial prosthesis gives a better and more precise adaptation thanks to the supports cast on the occlusive surface of the natural tooth, which brings a greater force of mastication. Stability, strength, retention and strength are advantages of the partial metal prosthesis.
Thermoplastic hooks, either transparent or pink like the gum, can replace the metal hooks. In some cases, the conventional metal hooks are less discreet, which improves aesthetic appearance.
It is important, before starting the fabrication of metal partial dentures, to meet a dentist to have a complete examination of the mouth and to make sure that the remaining teeth are free of cavities and suitable for receiving the metal hooks made-to-measure. You must also meet a dental hygienist to have a complete cleaning of the remaining teeth.
Discreet and aesthetic
Little adjustment needed
Do not disturb the movements of the tongue
Metal conducts heat and cold
Does not damage the natural teeth on which it is based
The base to the acrylic partial denture is entirely made of acrylic and is manufactured with or without hooks. However, it is less comfortable and less stable than the partial metal prosthesis. It tends to compress tissue adjacent to the remaining teeth as it does not contain occlusal metal support on natural teeth. With the years, the teeth will tend to take off and move.
The acrylic partial denture is more recommended as a transitional prosthesis to patients who presume the loss of natural teeth in a short time. Therefore, this will require the modification of their acrylic partial denture.
